I’ve been working on this as a side project off and on for a little while now. I’ve always been interested in belt driven extruders, because they theoretically have more responsive retraction than a geared design. I also wanted something that had as absolutly as short a distance between the hobbed things to the hotend as possible, used a Bondtech dual drive hob core, had an easy to access idler. and was stiffer on the mount than other designs. And thus, this extruder was born.
Presenting, the Alpha revision of the Nova Pro Belted Precision Extruder! (lots of pictures, files further down along with more details)
